Today, we discuss the possibility of humanity being alone in the galaxy or perhaps even the greater universe. We consider just how improbable our existence is by evaluating both the number of potential sites for life within our galaxy alone as well as the probability of abiogenesis occurring elsewhere. ►Click here to subscribe: https://www.youtube.com/channel/UCB0fFWQLZ2oj-FaoDUG_wow?sub_confirmation=1 ►Written, Produced & Narrated by David ►Share this video: https://youtu.be/yyVJkbUbzxY Music: “Cylinder Five” by Chris Zabriskie “Cylinder Eight” by Chris Zabriskie “Stories About the World That Once Was” by Chris Zabriskie

It isn't everyday that humanity touches down on other celestial bodies and this week, the OSIRIS-Rex spacecraft successfully touches the asteroid known as Bennu and managed to collect a sample to bring home to Earth. I thought it would be fun to get together ans show some highlights of the amazing event. Support Deep Astronomy and buy cool astronomy gear from OPT at the same time!

SPARC is aiming to be the first experimental device to achieve an energy-positive fusion reaction. New research suggests that this goal may soon be within reach. » Subscribe to Seeker! http://bit.ly/subscribeseeker » Watch more Elements! http://bit.ly/ElementsPlaylist » Visit our shop at http://shop.seeker.com With construction slated to begin in spring 2021, the team predicts it could be built within 3 to 4 years from that. Their goal is to achieve a Q factor of at least 2, basically meaning SPARC will pump out twice the energy needed to power it. Actually, by the calculations in their papers, SPARC could possibly achieve a Q ratio of 10! But the researchers are cautious about overpromising, and are just focused on achieving the lower figure. It’s still impressive, considering any net gain would be a first for human created controlled fusion. Assuming it gets built along that predicted 3-4 year timeline and actually gets flipped on, there’s still several steps between SPARC and limitless clean energy. #sparc #climatechange #fusion #technology #physics Read More: We've Long Waited for Fusion. This Reactor May Finally Deliver It—Fast. https://www.popularmechanics.com/science/energy/a34224299/nuclear-fusion-compact-reactor-sparc-timeline/ "Everyone involved with fusion is working hard with extremely complex science, and the delays aren’t because anyone is foolish." Compact Nuclear Fusion Reactor Is ‘Very Likely to Work,’ Studies Suggest https://www.nytimes.com/2020/09/29/climate/nuclear-fusion-reactor.html "...in seven peer-reviewed papers published Tuesday in a special issue of The Journal of Plasma Physics, researchers laid out the evidence that Sparc would succeed and produce as much as 10 times the energy it consumes." Nuclear Fusion Will Not Save Us https://earther.gizmodo.com/nuclear-fusion-will-not-save-us-1844605848 "Reducing emissions will require more than finding the perfect clean energy source; it will need a massive shift in human behavior, lowering our emissions through energy efficiency and less consumption." ____________________ Elements is more than just a science show.

Visit our sponsor, Brilliant: https://brilliant.org/IsaacArthur/ To become an Interplanetary Species we need to colonize another planet, and Mars will be our first target. To establish a base there, and a future settlement, we need to get their first, so we will also examine the Aldrin Cycler, a type of spacecraft that may make traveling to other worlds far easier.

We typically imagine interstellar civilizations as vastly superior in technology to modern times, but could the future see planets colonized by spaceships little better than our modern ones? Could some alien worlds allow space travel to develop far sooner and easier than it did on Earth? Or could civilizations abandon more advanced technology?
